Modular DC power system suits telecoms

Unipower has announced a modular DC power system designed to meet the exacting requirements of telecom systems applications, where reliability, flexibility and battery backup are key factors.

The Gravitas X410R DC power system is built around a compact 600 x 600 x 2134mm (48U) freestanding enclosure incorporating eight positions for hot-swap rectifiers, AC input and DC load distribution/protection, low-voltage battery disconnect, battery distribution/protection, system controller, and two or three shelves of front-connect batteries rated up to 185AH each.

A vertical space of 12U rack height has been allocated below the power components for optional equipment such as inverters or DC/DC converter shelves and their distribution/protection panels, customer-supplied equipment, or for an available third battery tray.

According to Unipower’s European marketing director, Nigel Frey, the DC power system supports 48V DC loads up to 400A (21.7kW) and can accommodate a variety of AC inputs from single or three-phase sources.

Frey said: ‘This mid-size DC power system will interest anyone looking to put together a telecom power source that can be specified to meet their exact needs and is simple to install.

‘Users will also appreciate the system’s front-access battery terminals and field-installable circuit breakers.’ The Gravitas X410 has the facility for up to 36 load circuit breakers.

These field-replaceable breakers can be connected to external loads as well as internally installed equipment.

The X410 is available as an open rack or as a fully enclosed system with top cover, removable side panels, lockable, hinged rear door and a convenient lockable, double front door.
